Wind Energy - Taking Concrete Steps To Save Power
Basic Information On Wind Energy
Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. At the end of 2008, worldwide nameplate capacity of wind-powered generators was 121.2 gigawatts (GW).
Wind power produces about 1.5% of worldwide electricity use,Wind Power Increase in 2008 Exceeds 10-year Average Growth Rate and is growing rapidly, having doubled in the three years between 2005 and 2008. Several countries have achieved relatively high levels of wind power penetration, such as 19% of stationary electricity production in Denmark, 11% in Spain and Portugal, and 7% in Germany and the Republic of Ireland in 2008. As of May 2009, eighty countries around the world are using wind power on a commercial basis.
Large-scale wind farms are typically connected to the local electric power transmission network; smaller turbines are used to provide electricity to isolated locations. Utility companies increasingly buy back surplus electricity produced by small domestic turbines. Wind energy as a power source is attractive as an alternative to fossil fuels, because it is plentiful, renewable, widely distributed, clean, and produces no greenhouse gas emissions; however, the construction of wind farms (as with other forms of power generation) is not universally welcomed due to their visual impact and other effects on the environment.
Wind power is non-dispatchable, meaning that for economic operation all of the available output must be taken when it is available, and other resources, such as hydropower, and standard load management techniques must be used to match supply with demand. The intermittency of wind seldom creates problems when using wind power to supply a low proportion of total demand. Where wind is to be used for a moderate fraction of demand, additional costs for compensation of intermittency are considered to be modest.
Studies of a pan european power grid, show that wind can be used to meet eg 70% of load, over a wide area of interconnected grids, and then the costs of electricity delivered into the consuming country are comparable to present day power costs. http://www.claverton-energy.com/talk-by-dr-gregor-czisch-at-the-5th-claverton-energy-conference-house-of-commons-june-19th-2009.html
Wind Power and 21st Century Energy Needs
Understanding and appreciating these important factors, wind power us moving further towards center stage when it comes to alternate energy options. Through this article, an exploration of the role wind power is likely to pay in the future is presented for your consideration.
Although wind power is not a perfect energy source - wind power is subject to weather changes and related turns of events beyond the control of humankind - it nevertheless is proving to be a solid and relatively reliable source of power in this day and age. In point of fact, wind power today is proving itself both to be one of the most environmentally friendly energy resources today. Moreover, wind power is becoming more economical all of the time - particularly when contrasted with the exploding costs associated with the more traditional carbon based energy resources.
As mentioned a moment ago the environmental impact of wind powers and wind turbines on the environment is minimal. Yes, wind turbines do take up space and they are large structures that are difficult to conceal. However, as a general rule, wind turbines do not have an appreciable effect on the flora or fauna of any location at which they are placed.
As was also noted previously in this article, wind power has become far more economical in recent years. In this regard, the costs associated with wind power and related technology has decreased by more than 80% of what it was a mere two decades ago. In other words, it has become significantly cheaper to develop, construct and utilize wind turbines for the generation of power in this day and age than it was in the 1980s. Further, unlike more traditional energy resources, these costs are expected to continue to decrease at a fair clip into the future as well. In fact, no expert predicts that the costs associated with wind power will do anything but decrease.
The total amount of power that is being generated through the use of wind turbines is increasing at a solid rate. In one year alone - from 2006 to 2007 - the amount of power generated through wind turbines jumped by a remarkable 20 gigawatts - from 74 gigawatts in 2006 to 94 gigawatts in 2007. The annual market share associated with wind power is increasing more than 30% each year.
In summary, the future looks very bright for wind power. As an increasingly inexpensive and definitely environmentally friendly source of power, the use of wind power and wind turbines to generate electricity is expected to continue apace steadily into the future.

Wind power solutions work best when the following conditions are met:
- You need to draw water from external sources. You can install a wind power system even when you do not need to draw water from outside. However, if you need to draw water from outside on a regular basis, a wind power system offers the best solution.
- Your house needs a lot of uninterrupted power supply. Combating those power outages is easy with the pollution-free wind power systems. You need no longer worry about a break in your work because of a power uncertainty.
- The average wind speed in your area is around 11 miles per hour. If you stay in a place that has little wind flow, your system will not work. Consult an expert before installing the wind power solution at home.
- You have a house or farmhouse spread over a big area. Typically, wind power solutions are employed in areas that spread over an acre.

I just watched a video about using kites to generate electricity. It was stated that the demo kite, about the size of a piano, could generate enough power for 4-6 houses. In some cases these could easily share the same space as windmills, make the same space even more productive.
